通过 homebrew 安装 opencv 🔗
通过 homebrew 安装在 Mac OS X 上安装为 Python3.5 安装 Opencv3：
$ brew install opencv3 --with-python3
......
......
This formula is keg-only, which means it was not symlinked into /usr/local.
opencv3 and opencv install many of the same files.
Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:
LDFLAGS: -L/usr/local/opt/opencv3/lib
CPPFLAGS: -I/usr/local/opt/opencv3/include
==> Summary
安装完成后，会有如上提示。接下来需要做的事，将 opencv3 的 site-packegs 链接到 Python3 的 site-packegs:
echo /usr/local/opt/opencv3/lib/python3.5/site-packages >> /usr/local/lib/python3.5/site-packages/opencv3.pth
检查是否安装成功 🔗
$ python
>>> import cv2
>>> cv2.__version__
